Description

TECHNICAL FIELD OF THE INVENTION

The present invention generally relates to inflatable balloons, and more particularly to a self-triggering inflatable balloon device.

BACKGROUND OF THE INVENTION

Balloons are commonly used as festive decorations to signify the celebration of some important event or anniversary. Balloons are universally recognized as a sign of happiness and celebration. It is therefore commonplace to purchase one or more balloons to give as a gift when celebrating a significant occasion.

Helium-filled balloons and other balloons inflated with gases that make them buoyant under normal atmospheric conditions are by far the most popular type of balloon. Such balloons are by perceived necessity sold to consumers already inflated with the buoyant gas because most consumers to do not possess means to inflate them. These inflated balloons have a limited life span, owing to the tendency of the balloons to deflate over time as the buoyant gas leaks from the interior of the balloon to the exterior, either through the inflation orifice or through the balloon material itself. Also, inflated balloons are very bulky and fragile, exhibiting explosive decompression if damaged in any way.

Because of the limited life span and the bulky and fragile nature of inflated balloons, it is not practical to send them through the mail. The cost of mailing is prohibitive due to the size of the balloon, and the odds of the balloon arriving at its destination inflated are small, it being likely that the balloon will deflate during transit due to leakage or damage. For the same reasons, it is generally not practical to gift wrap balloons and give them as presents.

Because of these limitations in past balloon technology, it was generally impractical or infeasible to send an inflated balloon to someone through the mail or to give balloons as gift-wrapped presents due to their bulky nature and due to the delay between sending or wrapping and receipt.

In response to this problem, I invented the self-triggering inflatable balloon device described in U.S. Pat. No. 5,579,813, the disclosure of which is hereby incorporated herein in its entirety.

As shown in FIG. 1, the self-triggeringinflatable balloon device 10 of my U.S. Pat. No. 5,579,813 includes abox 12 having alid 14, with aballoon 18 contained therein in an initially deflated state. Thedevice 10 includes acontainer 20 filled with a compressed gas. In a preferred embodiment, thecontainer 20 is a metal cylinder filled with helium gas. Thecylinder 20 is prevented from moving within thebox 12 by securing it to the interior thereof by any suitable means, such as by means ofU-clips 22.

Gas is prevented from escaping thecylinder 20 by means of avalve 24 connected to an end thereof. The other end of thevalve 24 is coupled to an opening in theballoon 18. Thevalve 24 includes anactuating handle 26, which maintains thevalve 24 in a closed state when in the position shown in phantom. However, rotation of theactuating handle 26 through 90° (in a clockwise direction as viewed in FIG. 1) is operative to place thevalve 24 in an open state. In the open state of thevalve 24, the compressed gas held within thecylinder 20 is free to flow through thevalve 24 and into theballoon 18, thereby expending theballoon 18. The amount of gas within thecylinder 20 and the pressure thereof is chosen such that theballoon 18 will become substantially fully inflated upon the opening of thevalve 24.

Theactuating handle 26 of thevalve 24 is coupled to amember 28, such as a wire, string or the like, which is coupled at its other end to the underside of thelid 14. Thewire 28 is threaded through an anchor point on the interior of thebox 12, such as through thedouble pulley 30. It will be appreciated by those skilled in the art that when thelid 14 is lifted in a vertical direction, it places tension on thewire 28. This tension is transferred to the actuatinghand 26, and causes theactuating handle 26 to be rotated to its open position as thelid 14 is lifted. At this point, theballoon 18 automatically inflates by means of the pressurized gas escaping from within thecylinder 20. Once the balloon inflation process has begun, it cannot be stopped or reversed by attempting to close thelid 14. The self-triggeringinflatable balloon device 10 is illustrated in its inflated state and the actuatinghand 26 of thevalve 24 is illustrated in its open state in the view of FIG. 1.

In practice, I have found that the operation of thevalve 24 by movement of thehandle 26 creates an undesirably high level of resistance to the opening oflid 14. There is therefore a need for a valve for use in a self-triggering inflatable balloon device that does not create an undesirably high level of resistance when opening the box lid. The present invention is directed toward meeting this need.

SUMMARY OF THE INVENTION

The present invention relates to a self-triggering inflatable balloon device. In a preferred embodiment, the device comprises a cylinder of compressed gas having an actuating valve thereon. The other end of the actuating valve is coupled to a deflated balloon. The cylinder, valve and deflated balloon are secured to the interior of a box having a lid. An actuating member of the valve is coupled to the box lid such that the valve is opened when the box lid is raised. Upon opening of the box lid, therefore, the actuating valve is opened and the balloon is automatically inflated with the gas from the compressed gas cylinder. The device may be given as a gift wrapped present or mailed to a friend, and will produce a surprise when opened.

In one form of the invention, a valve for a self-triggering inflatable balloon device is disclosed, comprising casing having an exterior, an interior, and an aperture for coupling a compressed gas container thereto and a nipple for coupling a balloon a valve thereto; a spike contained within the valve casing; biasing means disposed between the spike and an interior surface of the valve casing, wherein the biasing means urges the spike toward the aperture; and a trigger extending from the exterior to the interior of the valve casing, wherein the trigger limits movement of the spike toward the aperture; wherein removal of the trigger from the valve casing enables the biasing means to propel the spike into the aperture, thereby allowing compressed gas within the container to escape into an interior of the balloon, thereby inflating the balloon.

DESCRIPTION OF THE PREFERRED EMBODIMENT

For the purposes of promoting an understanding of the principles of the invention, reference will now be made to the embodiment illustrated in the drawings and specific language will be used to describe the same. It will nevertheless be understood that no limitation of the scope of the invention is thereby intended, such alterations and further modifications in the illustrated device, and such further applications of the principles of the invention as illustrated therein being contemplated as would normally occur to one skilled in the art to which the invention relates.

Referring now to FIG. 2, there is illustrated a preferred embodiment of the self-triggering inflatable balloon device of the present invention, indicated generally at 110. The present invention is completely enclosed in a suitable enclosure, such as abox 112, which may be made of any suitable material, such as cardboard or wood. Thebox 112 includes an openable portion, such as alid 114, which is hingedly attached to thebox 112 at one end by means of any suitable connection, such as a crease in the cardboard or by means of discreet hinges 116. Thelid 114 may optionally include opening instructions thereon, such as the message "PULL HERE." With thelid 114 closed upon thebox 112, the present invention may be gift wrapped or mailed to remote locations. When the recipient of thebox 112 opens thelid 114, aballoon 118 is caused to be automatically inflated from within thebox 112, by means which will be described in greater detail hereinbelow.

It will be appreciated by those skilled in the art that by means of the present invention, a deflatedballoon 118 may be enclosed within thebox 112 for an indefinite period of time and also mailed to a remote location without substantial risk of damage to theballoon 118. Because theballoon 118 is only inflated upon the lifting of thelid 114, there is not concern that the gas within theballoon 118 will leak therefrom prior to receipt of theballoon 118 by its intended recipient. Furthermore, because theballoon 118 is packaged in a deflated state, thebox 112 does not have to be large enough to contain the large and bulky size of the inflated balloon. For this reason, the self-triggeringinflatable balloon device 110 of the present invention may be easily stored, wrapped, mailed or transported. It will be further appreciated by those skilled in the art that any suitable message, picture or design may be imprinted onto theballoon 118 in order to convey a message to the recipient. For example, theballoon 18 illustrated in FIG. 1 is imprinted with the words "HAPPY BIRTHDAY" such that a birthday greeting is automatically presented to the recipient upon lifting thelid 114.

Referring now to FIG. 3, the self-triggering inflatable balloon device of the present invention is illustrated in cross-section. In the view of FIG. 3, thebox 112 is shown with thelid 114 closed, and with theballoon 118 in a deflated state.

Thedevice 110 includes acontainer 120 filled with a compressed gas. A preferred embodiment of the present invention, thecontainer 120 is a metal cylinder filled with carbon dioxide gas. However, the present invention comprehends the use of any suitable gas, such as helium or nitrogen. Thecylinder 120 is prevented from moving within thebox 112 by securing it to the interior thereof by any suitable means, such as by means ofU-clips 122.

Gas is prevented from escaping thecylinder 120 by means of avalve 124 connected to an end thereof. A second end of thevalve 124 is coupled to an opening in theballoon 118. The present invention comprehends the use of anysuitable balloon 118, such as a latex or Mylar balloon. Thevalve 124 includes anactuating trigger rod 126 which is operative to cause thevalve 124 to puncture thecylinder 120 when therod 126 is removed from theslot 128 formed within thevalve 124, as discussed in greater detail hereinbelow. Puncturing thecylinder 120 causes the compressed gas held therein to escape from thecylinder 120, through thevalve 124, and into the interior of theballoon 118, thereby causing theballoon 118 to inflate. The amount of gas within thecylinder 120 is chosen such that theballoon 118 will become substantially fully inflated upon the puncturing of thecylinder 120.

Theactuating rod 126 is coupled to the interior side of thelid 114 by any convenient means, such as a loop oftape 130. The length of thetape 130 extending from the surface of thelid 114 is chosen such that opening thelid 114 causes tension to be placed upon thetape 130, thereby pulling theactuating rod 126 from theslot 128 and activating thevalve 124. Therefore, when thelid 114 is raised, theballoon 118 automatically inflates by means of the pressurized gas escaping from within thecylinder 120, through thevalve 124, and into the interior of theballoon 118. Once the balloon inflation process has begun, it cannot be stopped or reversed by attempting to close thelid 114.

It will be appreciated by those skilled in the art that the self-triggering inflatable balloon device of the present invention allows theballoon 118 to be maintained in a deflated condition until the balloon is received by the intended recipient, thereby allowing thedevice 110 to be stored for indefinite periods of time after purchase without the danger of the inflation gas leaking therefrom. This will allow thedevice 110 to be purchased well in advance of the occasion for which it was purchased, and will also allow thedevice 110 to be gift wrapped and presented to the recipient in advance of the time designated for opening the device. Furthermore, because theballoon 118 remains in a compact, uninflated state within thedevice 110, thedevice 110 can readily be transported or mailed to a remote location. Thedevice 110 is illustrated in FIG. 4 in its inflated position, wherein it can be seen that theactuating rod 126 has been pulled from theslot 128 in thevalve 124, and now hangs from thelid 114 by means of thetape 130.

Referring now to FIGS. 5A-C, the external casing for thevalve 124 is illustrated. The casing for thevalve 124 is preferably formed from injection molded plastic, however those having ordinary skill in the art will recognize that thevalve 124 may be formed from any desired material, including machined aluminum. Thevalve 124 includes amain body portion 132 into which theslot 128 is cut. A threadedaperture 134 is formed into one end of thecasing 132. The threadedaperture 134 is sized so as to allow thecompressed gas cylinder 120 to be threadedly coupled thereto. A second,non-threaded aperture 136 is formed into the opposite end of thecasing 132. Apassageway 138 is formed in thecasing 132 so as to couple theapertures 134 and 136. Anipple 140 is formed onto a top surface of thecasing 132, thenipple 140 providing convenient means for mounting theballoon 118 to thevalve 124. Aninternal passageway 142 is formed within thenipple 140 and intersects theaperture 134 and thepassageway 138. Four threadedholes 144 are formed into the end of thecasing 132 around the opening of theaperture 136. These threadedholes 144 allow the mounting of a cover 146 (see FIG. 6) to thevalve 124 by means of four screws (not shown).

Assembly of the remaining components of thevalve 124 into thecasing 132 is illustrated in an exploded partially cross-sectional view in FIG. 7. Puncturing of the membrane sealing thecompressed gas cylinder 120 is accomplished by means of ametal spike 148 mounted into acylindrical slug 150. Theslug 150 is preferably formed from injection molded plastic. Theslug 150 includes anannular recess 152 around one end thereof in order to facilitate mounting aspring 154 around theslug 150. The annular recess forms aridge 156 around the circumference of theslug 150, thereby preventing thespring 154 from moving past thisridge 156. Thecylindrical slug 150 is formed such that its maximum diameter is just slightly smaller than the internal diameter of theaperture 136. Furthermore, the maximum diameter of thespike 148 is formed to be slightly smaller than the internal diameter of thepassageway 138.

Thevalve 124 is shown in its assembled and cocked position in FIG. 8. It can be seen that the presence of theactuating trigger rod 126 within theslot 128 prevents thecylindrical slug 150 from moving to the left of theslot 128. This causes thespring 154 to be compressed between thecircumferential ridge 156 of theslug 150 and theend plate 146 coupled to thecasing 132. With thevalve 124 in this cocked position, thecylinder 120 is screwed into theaperture 134 such that the membrane on the end of thecylinder 120 faces thepassageway 138. Thecylinder 120/valve 124 is then mounted to the interior of thebox 112 as shown in FIG. 3. Theballoon 118 is placed onto thenipple 140, and thetape 130 is attached to the underside of thelid 114.

Thereafter, once thelid 114 is raised, tension on thetape 130 causes theactuating trigger rod 126 to be pulled from theslot 128. Removal of theactuating rod 126 frees the only obstacle to movement of thecylindrical slug 150 within theinternal aperture 136. Therefore, the force exerted against theslug 150 by thecompressed spring 154 acts to drive the slug rapidly to the left, whereby thestake 148 passes through theinternal passageway 138 and into theinternal aperture 134, thereby puncturing the membrane on the end of thecylinder 120. Puncturing the membrane on the end of thecylinder 120 allows the compressed gas therein to escape, this compressed gas moving through theinternal passage 142 and into the interior of theballoon 118, thereby causing theballoon 118 to inflate. Pressure of theslug 150 against the interface between theinternal aperture 136 and theinternal passageway 138, as well as the substantial filling of thepassageway 138 by thestake 148, substantially eliminates any flow of compressed gas through thepassageway 138. Therefore, all of the compressed gas within thecylinder 120 will be routed to the interior of theballoon 118 through thepassageway 142. The diameter of thepassageway 142 is chosen so as to achieve the desired rate of inflation of theballoon 118.

It will be appreciated by those skilled in the art that various features of the preferred embodiment as disclosed herein may be modified. For example, it is possible to require that thelid 114 of thebox 112 be slid open, thereby also pulling theactuating rod 126 from theslot 128. Furthermore, it is not necessary that theballoon 118 be attached directly to thevalve 124. For example, a length of tubing may be coupled between theballoon 118 and thevalve 124 in order to allow theballoon 118 to rise farther out of thebox 112 once thelid 114 has been raised.

While the invention has been illustrated and described in detail in the drawings and foregoing description, the same is to be considered as illustrative and not restrictive in character, it being understood that only the preferred embodiment has been shown and described and that all changes and modifications that come within the spirit of the invention are desired to be protected.
